CO: Fall is a Critical Time for Preventing Bear Conflicts

GRAND JUNCTION, Colo. – For Colorado residents, September’s
shorter days and cool, crisp mornings signal that it’s time to wrap
up summer projects and prepare for winter weather. For black bears,
the arrival of fall is more like a warning: “Time to eat as much as
possible – if you want to live.”

With bears now entering their binge-eating season, Colorado
Parks and Wildlife managers are urging residents and visitors to
take special care to secure trash, birdseed and other easy sources
of food. Bears that learn to find meals around homes and businesses
often become problem bears that end up being destroyed, wildlife
managers say.

“It’s just amazing how much one bear needs to eat,” said
Watchable Wildlife Coordinator Trina Romero. “And that’s the only
thing bears care about right now – eating nearly everything in

Black bears don’t technically hibernate – it’s more like a long
sleep. However, the result is the same – Colorado bears need to
pack on enough fat to survive four or five months without a meal,
so during late summer and fall, bears enter a condition called
“hyperphagia,” which compels them to eat for as much as 20 hours a

During hyperphagia, a bear may increase its intake of food from
8,000 calories to 20,000 calories per day. That’s about the number
of calories found in 70 McDonald’s cheeseburgers. While Colorado
bears have evolved to survive on a diet of berries, acorns and the
occasional prey item, they will readily take advantage of an easy
meal consisting of trash or poorly stored food. Every year, the
combination of hungry bears and careless humans creates conflicts
that Colorado’s wildlife managers are charged with sorting out.

The typical consequences of poor food and trash storage are a
garbage-strewn lawn or a camping trip cut short. In some cases, it
can even lead to a damaged kitchen. However, for bears, the
consequences are often fatal. Because a wildlife manager’s priority
is human safety, problem bears are tranquilized and relocated only
once. The second time they get in trouble, they are destroyed. So
are bears that enter homes or show aggression toward people just

“It’s unfortunate, but some bears are killed simply because
people can’t be bothered to secure their food or trash,” said Area
Wildlife Manager JT Romatzke. “Public safety has to be our first
priority, but I can tell you that putting a bear down because of
someone’s thoughtlessness is one of the worst parts of my job.”

The problem is compounded by a bear’s natural intelligence and
excellent memory. Once a bear learns how to get an easy meal, they
will apply that knowledge again and again in the following years.
Sows can teach their cubs the same behavior, creating a cycle that
can bring them into a conflict with people.

Although wildlife managers have the option to relocate a
nuisance bear, it is an option that is becoming increasingly
difficult as development continues to encroach on bear habitat. In
addition, it is not uncommon for relocated bears to return in
search of the easy meals that got them into trouble in the first
place, or resume their bad habits in their new habitat.

Although bears do not typically attack humans, they are large,
powerful animals and their determination to eat makes them
dangerous when they learn human items and places are a source of
food. This summer saw several high-profile incidents involving
bears that entered tents in search of food and injured the

“These bears were likely rewarded in the past and learned that
people and tents mean an easy meal,” said Area Wildlife Manger
Perry Will. “We do have concerns about some bears, but overall, we
have quite a few more concerns about people who don’t follow the

Colorado Parks and Wildlife is one of several government
agencies that conduct ongoing public education campaigns on living
with bears. The agency provides extensive information through their
website, pamphlets, media stories and even magazines and books. In
addition, they also dispatch volunteer “Bear Aware” teams to go
door-to-door in problem areas.

“It’s frustrating because this information is so easy to find,”
Northwest Regional Manager Ron Velarde. “There really is no excuse
in the majority of cases.”

According to Kevin Wright, the District Wildlife Manager in
Aspen, what’s especially disheartening for wildlife managers is how
quickly people who live in bear country forget about their
responsibility to help prevent problem bears.

“Considering the consequences, you’d think folks would learn the
first time a bear gets into their trash, or their home,” he
continued. “These should be habits that people practice year round.
But for too many people, we have to remind them again and

Complicating matters, a single person’s negligence can lead to
problems for many, explained Breckinridge Area Wildlife Manger
Shannon Schwab.

“A problem bear is everyone’s problem,” said Schwab. “If even
one person doesn’t care enough to take precautions and a bear gets
into their trash or their house, it increases the chances that the
bear will move on to the neighbor’s house, and so on. Multiply that
by thousands of bears across the state that are now preparing for
winter and you can see why it is so important for everyone to do
their part.”

Following the tips listed below is a good start to help reduce
conflicts around the home, however, many other tips regarding
hiking, camping and hunting in bear country can be found in
Colorado Parks and Wildlife’s website at:

Keep Bears Out

– Many bears that enter homes do so through an unlocked or open
window or door. Close and lock all bear-accessible windows and
doors when you leave the house, and at night before you go to

– If you must leave downstairs windows open, install sturdy
grates or bars. Screens don’t keep out bears.

– Keep garage doors and windows closed and locked when you’re
not home, or at night. Don’t leave your garage door standing open
when you’re not outside. Install extra-sturdy doors if you have a
freezer, refrigerator, pet food, bird seed, or other attractants in
your garage.

– Keep car doors and windows closed and locked if you park
outside. Make sure there’s nothing with an odor in your vehicle,
including candy, gum, air fresheners, trash, lotions and lip

– Bears are great climbers – remove any tree limbs that might
provide access to upper level decks and windows.

– Replace exterior lever-style door handles with good quality
round door knobs that bears can’t pull or push open.

– Put on talk radio (not music) when you leave home; the human
voice startles most bears.

Get Rid of Attractants

– Bears follow their super-sensitive noses to anything that
smells like food, and can follow scents from up to five miles

– Don’t leave trash out overnight unless it’s in a bear-proof
enclosure or container. Obey all local regulations.

– We recommend feeding birds only when bears are

Teach Bears They’re Not Welcome

– If a bear comes into your yard or close to your home, do
yourself and the bear a big favor, and scare it away. A confident
attitude plus loud noises like a firm yell, clapping your hands,
banging on pots and pans or blowing an air horn sends most bears

– If a bear enters your home, open doors and windows and make
sure it can leave the same way it got in. Don’t approach the bear
or block escape routes.

– Never approach a bear. If a bear won’t leave, call your local
CPW office. If a bear presents an immediate threat to human safety,
call 911.
